SMC Pentax-DA 70mm f/2.4 Limited Lens

The Pentax lens repertoire seems to have its fair share of prime or single focal length lenses, bucking the trend towards the ubiquitous zoom. Many of these Pentax primes are described as Limited, not in the sense of them having a short production life, but rather in the limited number that can be made of these hand assembled, superior optics. The price is relatively high, so the questions are do these lenses indeed have superior finish and construction and are they of a higher optical standard? We shall now attempt to find the answers.
